The present invention relates to a golf club headpad, made of a rubber-based material, which covers the head of a golf club or is attached to the head face such that an amateur golfer can reduce an impact between the golf club and a golf ball and increase a back spin of the golf ball, thereby increasing a flight distance of the golf ball in addition to reducing a hook and slice of the golf ball.

TECHNICAL FIELD

The present invention relates to an elastic rubber-based headpadattached to a head and a head face of a golf club in use, morespecifically, the present invention relates to a headpad of a golf club,in which a side spin of a golf ball hit by a head face of a golf club isreduced by increasing a back spin of the golf ball, a strike impactbetween the head face and the golf ball is reduced when hitting the golfball, and the headpad is a rubber-based product attached to the head andhead face of the golf club by applying adhesive or a separate fixingdevice, and in which the headpad of the golf club utilizes the gear mesheffect between the golf club head and the golf ball, the inertia lawbetween a billiard ball and a billiard cue in a billiard game, and theprinciple of a ball spin by a tip attached to an end of the cue.

BACKGROUND ART

The golf is a sport in which a golfer hits a golf ball by using a golfclub such that the golf ball gets into a hole cup at a smaller number ofstrokes. To this end, various golf clubs such as drivers, woods, irons,wedges and putters are used.

Among the golf clubs, the driver and the wood are used to make a longdriving distance, and the driver and the wood having the head face angleof about 10.5 degrees are mainly used, in which the main purpose of thedriver and the wood is to send the golf ball far away with an accuratehit.

Meanwhile, in the case of irons, various types of irons are used such asNo. 1 driving iron, No. 2 mid iron, No. 3 mid mashy, No. 4 mash iron,No. 5 mash, No. 6 spade mashy, No. 7 mashy niblick, No. 8 pitcher, No. 9niblick, a pitching wedge, and a sand wedge, and these irons have theirown distance and trajectory characteristics.

The main purpose of these irons is to approach as close as possible tothe hole cup on the green from the fairway. To this end, the golf clubheads have various weights and various head face angles so as to beselectively used depending on the situation.

However, in order to settle the golf ball close to the hole cup, it isimportant to minimize the run after the golf ball is seated on theground. For this purpose, a horizontal groove is formed on the head faceso that the golf ball is subject to a strong back spin when the golfball is hit, thereby preventing the run as much as possible.

The back spin not only allows the golf ball to be stopped in thevicinity of the drop point, but also helps the golf ball to increase thedriving distance by lifting force such as an airplane. For this reason,various related arts have been disclosed in relation to the shape of thehorizontal grooves.

In the head face of a conventional golf club head, for example,‘U’-shape or V′-shape horizontal grooves having a depth of 0.25˜1 mm anda width of 0.5˜1 mm are formed at an interval of less than 2.667 mm asshown in FIG. 1.

In this case, when the golf ball is hit, the golf ball is temporallydeformed into a planar shape corresponding to a face surface of the golfhead and is subject to a downward rotational force according to theangle of the face surface so that the back spin of the golf ball isincreased by jaws of the horizontal grooves.

In order to increase the rotational force of the golf ball by the jawsof the horizontal grooves, the depth (width) of the groove has to beincreased. However, in this case, although the rotational force can beincreased, there is a disadvantage that the driving direction may beunstable and the golf ball and the groove of the head face are severelyworn, so the above method is rarely used. In contrast, if the intervalof the grooves is narrow, the rotational force may not be effectivelytransferred, so a normal shape is provided for desired directionality.

However, such a conventional horizontal groove has a problem that lessrun occurs due to less rotational force in the case of an iron having arelatively short driving distance and the rotational force is remarkablyreduced in the rough.

In addition, when a golfer hits the golf ball using the head face ofeach golf club head, that is, when 1 to 16/392 (at most 51 to 76) in thesurface area of the golf ball makes contact with the head face of eachgolf club, a face angle is formed in the clockwise and counterclockwisedirections about a handle shaft and dimple joints (see reference numeral7 of FIG. 2, in which reference numeral 6 is a golf ball, and referencenumeral 8 is a plurality of concave grooves divided by the dimplejoints) of the golf ball when viewed from the top of the head face asshown in FIG. 3 and a lie angle (an angle between the shaft of the golfclub and the ground) is formed as the head part is lifted up and down asshown in FIG. 4. In addition, the side spin of the golf ball may begenerated due to the angle of sole of the golf club. Due to the sidespin of the golf ball, the driving direction of the golf ball may bechanged to the left and right (hook & slice), so the golf ball travelsin the direction other than the direction intended by the golfer,thereby causing the problem in the safety management of the golf courseand resulting in the delay of the golf game.

In the case of a golf club formed of a metal, as shown in FIG. 1, a golfclub head 1 is coupled to a shaft 10 at a heel part 11, and the golfclub head 1 includes a front head face 2, side surfaces 4 on left andright sides of a toe and a top surface 3 on an upper side.

The head face 2 includes horizontal grooves 5 in the form of slots. Inthe case of an amateur golfer, a shock generated when the head face 2erroneously hits the golf ball may be applied to fingers, wrists,elbows, shoulders, etc. of the human body through a shaft 10, so thereis a problem that the golfer has to be treated in the hospital. Inwinter, the above problems frequently occur when the golf ball cooled bythe atmospheric temperature makes contact with the head face formed ofmetal, and in the case of the driver, the wood, and the putter, highfrequency metallic noise occurs. In addition, when the golfer hits thegolf ball with the golf club formed of metal, the dimple joints of thegolf ball may directly come into contact with the head face, so thedriving direction of the golf ball may differ from the target directionintended by the golfer and this problem becomes serious in the case theputting.

DETAILED DESCRIPTION OF THE INVENTION Technical Problem

Therefore, the present invention is suggested to solve theabove-mentioned problems, and an object of the present invention is toprovide a golf club headpad, in which a side spin of a golf ball hit bythe headpad added to the golf club can be reduced by increasing thepower of the backspin, the side spin can be induced through the gearmesh effect so that the driving direction of the golf ball can be guidedinto the target direction intended by the amateur golfer, the strikeimpact between the head face of the golf club and the golf ball can bereduced so that the shock applied to the human body can be reduced, theback spin of the golf ball can be increased so that the driving distanceof the golf ball can be increased, and a sweet zone is displayed on theheadpad attached to the head face of the golf club to allow an amateurgolfer to easily identify the sweet zone.

Technical Solution

In the conventional golf club head, the head face makes contact with thegolf ball, 1 to 16/392 in the surface area of the golf ball makescontact with the head face. However, according to the present invention,the headpad is attached to the head and the head face of the golf clubso that the surface area of the golf ball making contact with the headface is increased to 6 to 32/392 (at most 51 to 76), thereby preventingthe dimple joints of the golf ball from making direct contact with thehead face. In addition, the side spin of the golf ball caused by theface angle, the angle of sole and the lie angle of the golf club isreduced by the gear mesh effect and the increased back spin. The drivingdistance of the golf ball can be increased due to the elasticity of theheadpad and the back spin of the golf ball, the change of drivingdirection caused by the direct contact between the dimple joints of thegolf ball and the head face can be reduced and the amateur golfer caneasily to identify the effective hitting surface through the sweet zonemarked on the head face of the golf club.

Advantageous Effects of the Invention

The present invention can reduce the side spin of the golf ball by usingthe elastic rubber-based headpad of the present invention, which isadded to the head and the head face of each golf club, can induce theside spin through the gear mesh effect such that the driving directionof the golf ball can be guided into the target direction, can reduce thestrike impact between the head face of the golf club and the golf ball,and can increase the driving distance of the golf ball.

According to the present invention, the distance determined by theamateur golfer when hitting the golf ball with the putter face formed ofmetal may be long or short depending on the hitting time and the outsidetemperature of the putter face and the golf ball. This problem can beprevented by the elastic headpad of the present invention. In addition,the fluctuation in the driving direction of the golf ball, which iscaused by the dimple joints of the golf ball, can be prevented by usingthe rubber-based headpad of the golf club. Further, in the case of thedriver, the wood and the putter, the high-frequency metal noise can beprevented so that the strike impact can be reduced as much as possiblein cold winter.

BEST MODE Mode for Invention

In the present invention, a material for a headpad 50 is a rubber-basedmaterial having elasticity and flexibility, and at the same time, has arestoring force so that the surface of the headpad deformed due to thehitting may be immediately recovered after the hitting. The flexibilityor elasticity may compensate for the excessive side spin applied to thegolf ball when hitting the golf ball and the golf ball may come intocontact with an anti-groove of the headpad that protrudes, therebyincreasing the back spin. The material for the headpad is notspecifically limited, and may include Ethylene Propylidene Rubber (EPR),Copolymer of Ethylene Propylidene Monomer (EPDM), natural rubber,polyurethane, silicone rubber, natural fiber, fiber, or mixed material.

As shown in FIGS. 6 to 9, the present invention includes an elastic faceplate 20 bonded to a head and a head face of the golf club or coveringthe head and the head face of the golf club in use and having a shapecorresponding to a head face portion.

The face plate 20 has horizontal anti-grooves 30 protruding from asurface of the face plate 20 at a predetermined interval and verticalanti-grooves 40 formed on both sides of the horizontal anti-grooves 30at a predetermined vertical interval, thereby forming the headpad 50 ofthe golf club.

The horizontal anti-grooves 30 and the vertical anti-grooves 40 may beconfigured such they protrude from the surface of the face plate 20attached a head face 2 of a golf club head 1 as illustrated in FIG. 8.The headpad 50 of the present invention may be attached to the head face2 of the golf club head 1 with an adhesive, or may be prepared in theform of a pocket that wraps the entire golf club head 1, but the presentinvention is not limited thereto.

In order to allow a user to recognize a hitting effective point, a sweetzone having a recognizable color may be added to a hitting point of theheadpad.

The horizontal anti-grooves 30 and the vertical anti-grooves 40 of thepresent invention may be configured such that grooves are formed atregular intervals on the surface of the face plate 20 attached to thehead face 2. For example, the horizontal anti-grooves 30 and thevertical anti-grooves 40 may be formed on a putter as shown in FIG. 9,an iron head as shown in FIG. 7, and a driver as shown in FIG. 6. Thehorizontal anti-grooves 30 may have a U-shape that protrudes, but thepresent invention is not limited to the shape of the anti-groove.

The material for the rubber-based pad 50 of the present invention mayinclude one or at least two of polyethylene, polypropylene,polyvinylacetate, polyvinyl chloride, silicone, and rubber, but thematerial is not specifically limited so long as the material has afunction of providing basic elasticity.

According to the present invention having the above configuration, thedriving distance of the golf ball can be increased by the horizontalanti-grooves 30 having elasticity of the headpad 50 and the back spin ofthe golf ball, the change in direction (hook & slice) caused by thecollision between the head face 2 and the dimple joints 7 of the golfball can be reduced, and the amateur golfer can easily identify thehitting point through the sweet zone of the headpad 50 attached to thehead face 2 of the golf club head 1. In addition, the horizontalanti-grooves 30 may absorb water droplets and the like stuck to thesurface of the golf ball through the grasses to prevent slipping whenhitting the golf ball, the hitting area with respect to the dimplejoints 7 of the golf ball 6 may be increased according to the elasticityand flexibility of the headpad 50, and the back spin of the golf ball 6may be increased, so that the side spin can be reduced, therebypreventing the hooks and slices of the golf ball and increasing thedriving distance of the golf ball.

Meanwhile, the present invention may include the vertical anti-grooves40 on opposite end portions of the horizontal anti-grooves thatprotrude. In the case of normal hitting, as shown in FIG. 5, when thehitting direction and the hitting force of the golf club head 1 act as aforce Fa, the corresponding golf ball 6 receives force Fa′ so that thegolf ball 6 travels in the direction of the solid line. However, at themoment when the amateur golfer hits the golf ball, the golf club head 1may be twisted in the direction of the force Fc from the direction ofthe force Fa due to the mistake or unskilled hitting. The above force istransferred to the golf ball 6 as the rotating force by the vector forceF11 so that the golf ball 6 also travels while rotating by the vectorforce F11 due to the gear mesh effect. Therefore, the movement pathbecomes uncertain depending on the strength of the force and thetopography of the land. However, according to the present invention, thecontact area with respect to the dimple joints 7 may be increased due tothe horizontal anti-grooves 30, and the horizontal anti-grooves 30 mayabsorb a part of the vector force F11 upon hitting, so that less vectorforce F11 may act, thereby reducing or preventing the erroneous hitting.

That is, when there is no headpad 50 of the present invention attachedto the golf club head 1 in use, the condition that the head face 2 makescontact with the golf ball 6 is 1 to 16/392 based on the surface area ofthe golf ball. However, when the headpad 50 is attached to the head face2 as in the present invention, the surface area of the golf ball 6 incontact with the face plate 20 of the headpad 50 at the time of hittingis increased to 6 to 32/392 (at most 51 to 76) because the contact areais increased due to the horizontal anti-grooves 30 of the headpad 50.Therefore, due to the front collision of the dimple joints 7 of the golfball 6 and the vector force F11 and the vector force F12 generated bythe face angle, the angle of sole and the lie angle, the power of sidespin of the golf ball 6 may be reduced due to the increase of the backspin caused by the headpad 50 of the present invention so that thecorresponding vector force F11 and vector force (F12) of the golf ball 6may be reduced.

In addition, the side spin of the golf ball 6, which is generated due tothe front collision of the dimple joints 7 of the golf ball 6 and thevector force F11 and the vector force F12 generated by the face angle,the angle of sole and the lie angle, can be induced by the gear mesheffect so that the driving direction of the golf ball 6 can be correctedto the target direction.
